SOCKET MEMBER FOR SEPARABLE FASTENERS.

SPECIFICATION forming part of Letters Patent N 0. 615,776, datedDecember 13, 1898. Application filed January 5, 1898. Serial No.665,695. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. ADAMS, a citizen of the United States, anda resident of New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in SocketMembers for Separable Fasteners; and I do hereby declare the followingtobe afull, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the letters of reference marked thereon.

This invention relates to that class of devices commonly known asseparable fasteners and adapted more especially for use upon gloves andother articles of wearing-apparel, although its use is by no meansconfined to this class.

The object of the invention is to produce an exceedingly simple andstrong device composed of a minimum number of parts and of suchcharacter that it may be readily attached to the goods by means of thewell-known appliances.

Referring to the accompanying drawings, Figure 1 is a sectional viewthrough a blank for thecap-piece of the fastening. Fig. 2 is a similarsection through the cap-piece and its cooperating eyelet with the partsseparated. Fig. 3 is a side elevation of the eyelet shown in Fig. 2 insection, which constitutes the chamber for the reception of the studmember. Fig. 4 is a sectional view taken through the two members, thecap and eyelet, showing their form after having been assembled andattached to the goods. Fig. 5 is a diagrammatic view showing one use ofthe device, the same being applied to a glove. Fig. 6 is a sectionalView corresponding to Fig. 4, but on an enlarged scale and with thegoods shown in dotted lines.

Like letters of reference in the several figures indicate the sameparts.

In the preferred embodiment of the invention and as illustrated theentire socket memher is composed of but two simple parts-=to wit, acap-piece and an eyelet. The cap-piece has the usual curved or crownedtop with a reduced entrance-opening, and the eyelet, which forms, ineffect, the chamber for the stud member, is constructed of such shapethat when passing into the cap-piece pressure Fig. 1, the edges of whichare subsequently drawn in to form an annulus or circularentrance-opening a, Fig. 2, of a diameter which will admit the barrel ofthe eyelet, to be now described.

The eyelet B is formed with an outwardlyextending base-flange b, of anyusual contour, on the external periphery and surface and with anupwardly-extending barrel or body portion, the walls B of which incross-section are of substantially ogee-curve form. At the point ofunion between the body or barrel B and the flange b the opening withinthe eyelet is consequently somewhat reduced and forms the engaging edgeof the socket member, and the enlargement immediately above the engagingedge constitutes the chamber for the head of the stud member.

Experimentation has demonstrated that when an eyelet of this peculiarform is pressed into the cap-piece and against the top surface thereofthe pressure will cause the upper portion of the eyelet-body to foldinwardly, making an annulus C, Fig. 6, the extreme edge of which isusually folded back upon itself, as at c, and in the formation of thisannulus C the portion of the eyelet adjacent and below the same isbulged outwardly, as at C, causing the body portion of the eyelet toexpand against the edge of the cap-piece at a, with the portion oflarger diameter within the cappiece. The result of this is that not onlyare the two parts locked firmly together, but there is a positivetendency of the eyelet to draw into the cap-piece, and thereby grip thegoods held between the cap-piece and the flange Z) of the eyelet. Thecap-piece by the pressure exerted in clamping the two parts together maybe set down a little, so as to present a somewhat flattened appearanceas compared with it before the parts are assembled and as shown in Figs.2 and 4. The effect of this flattening of the cap-piece is to formbetween the flange of the eyelet and the rim or edge of the cap-piece agripping edge at the periphery of the flange of the eyelet, permittingthe goods to expand slightly adjacent the body of the eyelet, therebyovercoming any tendency to tear out, and so permit the socket member tobecome released from the goods.

The entrance-aperture form ed by the angle between the flange Z) andbody B, it will be observed, is a rigid aperture, the device beingadapted for the accommodation of a resilient stud, while the chamberabove such aperture is of larger diameter. Furthermore, the annulus C isof larger diameter than the said entrance-aperture and does not obstructthe chamber, but, on the contrary, the head of the stud may pass intothe annulus when the parts are assembled and its surface approach closeto the cap, thereby producing a device which is but little thicker thanthe goods to which it is applied. In this connection it will also benoted that the edge of the eyelet turning back on itself at c insures alarge diameter for the annulus O for the accommodation of the stud andat the same time the edge being double affords sufficient strength toresist any inward bending or collapsing of the enlarged portion of theeyelet under excessive strain tending to draw the eyelet out of the cap.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A socket member for a separable fastener, comprising the cap-piecehaving its edge turned inwardly to form an annular entrance-opening, aneyelet forming the entrance-opening for the stud having anoutwardly-extending base-flange and an up wardly-extendingbody portion,bulged outwardly within the annular entrance-opening of the cap-piece tounite the parts and with its upper portion above such outwardlybulgedportion turned inwardly in the form of an annulus, said annulus being ofgreater diameter than the entrance-opening in the eyelet; substantiallyas described.

2. A socket member for a separable fastener comprising the cap piecehaving its edge turned inwardly to form an annular entrance-opening, aneyelet forming the entrance-opening for the stud having anoutwardly-extending base-flange and an upwardly-extending body portion,bulged outwardly, within the annular entranceopening of the cap-piece tounite the parts, with its upper portion above such outwardly-bulgedportion turned inwardly in the form of an a11- nulus of greater diameterthan the entrance opening in the eyelet and the extreme edge of saidbody portion doubled back on itself around the said anu ulus;substantially as de scribed.

3. An eyelet for forming one of the parts of one member of a separablefastener, having a base-flange and an upwardly-extending body portion,having a greater diameter than the opening through said flange, at apoint immediately above and adjacent thereto, a restricted portion abovesaid enlarged portion and with its upper edge flared or turnedoutwardly; substantially as described.
